Poser has problems with joints when they get past 90 degrees, Victoria's mesh just seems slightly worse than other for some reason. I tried to make it better on Supermodel Vickie (who's knees are just as bad) by adding Joint Controlled Morphs to adjust the mesh, I got it a lot better, but it was a ton of a lot of blind work (you never know exactly what a morph will do, I tried dozens of ideas). I don't know if (Jaeger's?) JCM for Vickie upgrade in the store addresses this or not, but if it does, it is a answer. Dina's knees work better, incidently, all of Dcourt's figures seem better here, some work a little strangely, but better.
